Technical Field
[0001] This utility model relates to the field of rice paddy spreading equipment, and in particular to a portable rice paddy heavy metal passivating agent spreader. Background Technology
[0002] Because heavy metals pose significant risks to the environment and human health, they can migrate with rainwater and groundwater, causing damage to soil and rivers. Furthermore, heavy metals are difficult to degrade in the natural environment, and their long-term accumulation can lead to a decline in land cultivation or ecological functions, as well as reduced crop yields. Therefore, passivating agents are needed to degrade heavy metals.
[0003] Before using the spreader, the passivating agent needs to be stored in the hopper in advance. Then, push the spreader so that the wheel drives the distributor to rotate, which delivers the passivating agent to the front of the spreader. The rotation of the distributor wheel then allows the passivating agent to be evenly spread on the land.
[0004] In the above-mentioned method, a distributor wheel is used to spread the passivating agent evenly. However, there are inevitably large clods of soil in the soil. Because the soil clods are dense and compact, the passivating agent cannot penetrate into the soil. Furthermore, the small contact area between the soil clods and the passivating agent will reduce the degradation effect of the passivating agent. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a portable paddy field heavy metal passivating agent spreader, which aims to improve the problem that the small contact area between soil clods and passivating agent will reduce the degradation effect of the passivating agent.
